First of all, let me show you what is unburned brick machine equipment?
Unburned brick machine equipment is a brick making machine that produces unburned bricks. The bricks produced can be used without burning. Unburned brick machine equipment is a new type of brick making equipment designed and manufactured in combination with the characteristics of similar products at home and abroad and market needs. Unburned brick machine equipment has the characteristics of compact structure, large pressing force, strong rigidity, full sealing and dustproof, circulation lubrication, simple operation, high output and durability. The feeder speed change and turntable rotation of the unburned brick machine equipment adopt the most advanced technology, with the advantages of large transmission force, stable operation, accurate in place and low maintenance rate. A new type of brick making equipment designed and manufactured in combination with the characteristics of unburned brick machine and market needs. Unburned brick machine equipment also has the characteristics of compact structure, large pressing force, strong rigidity, full sealing and dustproof, circulation lubrication, simple operation, high output and durability.
Unburned brick molds are divided into standard brick molds, hollow block molds, eight-hole brick molds, pavement brick molds and special-shaped brick molds. This is a basic classification, which may be used as the main structure. But in more detail, such as standard brick molds, hollow block molds, pavement tile molds, curbstone molds, etc.
When the unburned brick material is plastically deformed by pressure in the mold cavity, it flows and slides along the surface of the cavity, causing severe friction between the cavity surface and the material, which causes the mold to fail due to wear. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold. Hardness is the main factor affecting wear resistance. Generally speaking, the higher the hardness of the mold parts, the smaller the wear and the better the wear resistance. In addition, wear resistance is also related to the type, quantity, shape, size and distribution of carbides in the material.
The working conditions of the mold are mostly very bad, and it is easy to cause brittle fracture when it is subjected to a large load for a long time. In order to prevent the mold parts from breaking suddenly during production, the mold must have high strength and toughness. Carbon content and grain size are the standards for considering the strength and toughness of the material.
The unburned brick making machine production line is a cyclic process. The mold often leads to fatigue fracture under the long-term action of cyclic stress. It can be divided into small energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture performance of the mold mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.
When the working temperature of the mold is high, the hardness and strength will decrease, resulting in early wear of the mold or plastic deformation and failure. Therefore, the mold material should have high high temperature resistance to ensure that the mold has high hardness and strength at the working temperature.
Some molds are in a state of repeated heating and cooling during the working process, which makes the surface of the cavity tensile and pressure variable stress, causing surface cracking and peeling, increasing friction, hindering plastic deformation, and reducing dimensional accuracy, thus causing mold failure. Hot and cold fatigue is one of the main forms of mold failure. This type of mold should have high resistance to hot and cold fatigue.
In order to make the unfired brick making machine operate normally and safely, the mold should be maintained and repaired on the basis of material selection. Before each production run, check that each part is installed normally and there is no looseness in each component. Clean the material in the mold after production. Apply lubricating oil and paint to the mold in time to reduce mold friction and corrosion. Dongyue Machinery Group produces various types of unfired brick making machines, fully automatic and semi-automatic production equipment, and produces unfired standard bricks, hollow bricks, and porous blind bricks. One machine can be used for multiple purposes, which is efficient and labor-saving.
